SAN FRANCISCO, 26 APRIL 2011-Cisco Systems launched its first containerized data center on Monday, coming late to the party but offering some unique management features that could help set it apart from other vendors.
Containerized data centers typically are standard 20- or 40-foot shipping containers packed with servers, switches and other IT equipment. Pioneered by companies such as Verari Systems and Sun Microsystems, they're used to quickly add extra capacity to an existing data center or to bring capacity to a remote location, such as an oil exploration site or a battlefield.
Cisco has opted for a 40-foot container that it says can be up and running in 90 to 120 days from when an order is placed. Like other vendors in the market, Cisco expects customers to stock the containers primarily with its own products, but the racks inside can accommodate other vendors' equipment as well, said Keith Siracuse, a manager and product marketing engineer at Cisco.
Because they are small, self-contained environments, containerized data centers can be made highly energy-efficient. Cisco has gone a step further than other vendors by designing racks that each have their own enclosure, so the temperature for each can be set individually.
That allows customers to operate individual racks at slightly warmer or cooler temperatures, depending on the equipment inside and the workload, which helps squeeze out more energy savings.
The container can house up to 16 racks, with a maximum power capacity of 25 kW per rack. The containers can be parked side by side or stacked two deep to save floor space.
"You're able to put a lot more equipment, and get much better power utilization, versus the floor space in a traditional data center," Siracuse said.
Cisco opted for a chilled water cooling system that is housed in the floor of the container, under the racks. That means equipment is less likely to get damaged in the event of a water leak, he said. Most other vendors run the chilled water above the servers. Leaks aren't a common occurrence, but it's a concern that data center operators sometimes cite when considering water-based cooling systems.
The container comes with a new management tool, Cisco Data Center Operations 360, which monitors the rack temperature and other variables in real time and generates historical reports for analysis.
Customers can set the desired temperature range for each rack, and the software adjusts the fan speeds and water flow accordingly. Operations 360 also has tools for capacity planning and to design the layout inside the container.
Containerized data centers can be located next to an existing facility, where they share the same backup generator and water supply. If they are used remotely, the infrastructure is housed in a separate container.
